For each of the 3 choices of hat there are 2 choices of shorts. Therefore there are 3 * 2 combinations of hat and shorts. Each of these 3 * 2 combinations of hat and shorts can be combined with each of the 5 choices of shirt.
Therefore the number of combinations of 1 hat, 1 shirt and 1 pair of shorts is given by:
To find the cofactor of
![A=\left[\begin{array}{ccc}7&5&3\\-7&4&-1\\-8&2&1\end{array}\right]](https://tex.z-dn.net/?f=A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D7%265%263%5C%5C-7%264%26-1%5C%5C-8%262%261%5Cend%7Barray%7D%5Cright%5D)
We cross out the Row and columns of the respective entries and find the determinant of the remaining 
matrix with the alternating signs.
Therefore in increasing order, we have;
Answer:
Therefore he paid $10440 in 4 year.
Step-by-step explanation:
Given, Rachit borrowed $15000 from his friend. He gave $3000 at the rate 15% for 4 year.
Interest(I₁)= Prt here P= $3000, r=15% and t = 4 year
=$(3000×0.15×4)
=$1800
He gave $(15000-3000)= $12000 at the rate of 18%.
Interest(I₂)= Prt here P= $12000, r=18% and t = 4 year
=$(12000×0.18×4)
=$8640
Therefore he paid =$(1800+8640)=$10440 in 4 year.
The study of explanatory or independent differences based on the dependent variable is a simple statistical method. The correlation between two variables is researched in which only the explanatory variable of them would be present, and the further discussion can be defined as follows:
For point (i):
- The log(distances) seem to be optimistic, and their valuation is 0.312, which also means that the cost of a house will rise even as the distance increases.
- In this, the certainly is what everybody expects the better the house from the sewage treatment is from a hygienic viewpoint.
For point (ii):
- In this regard, we cannot use straightforward regression, even as non-biased price estimation might not even be provided.
- The price-distance relationship here is not so much linear.
For point (iii):
- Several factors influence the house's price, the biggest contributor is house length, market nearness or public areas, number of rooms, etc.
- Thus the only influence is not the mere distance from the incinerator. It's one of the factors affecting housing pricing.
- The proximity of markets and places can be connected to the distance from the crematorium.
- However, factors such as house size and the number of stories aren't related to the distance from the incineration plant.
